Connecting the TN-USB3-xx-01
This section describes how to connect the TN-USB3-xx-01 to a PC/Notebook/Tablet. The
TN-USB3-xx-01 can be used to allow a portable device, like a laptop or tablet computer,
to connect to a fiber based Gigabit Ethernet network, via its USB 3.0 port, providing
secure network access over a fiber infrastructure.
TN-USB3-xx-01 Connections
The figure above shows USB 3.0 connections for a TN-USB3-xx-01 to a desktop PC, a
laptop PC, and a tablet. The procedure is provided below.
1. Insert the TN-USB3-xx-01 USB connector into an available USB 3.0 port on your
computer or device.
Note: For maximum performance, connect the TN-USB3-xx-01 directly to a USB 3.0
port on your computer.
If you are connecting to a USB hub, make sure it operates at USB 3.0 speed and can
provide the required power for this device. A USB 2.0 hub will also work, but only at
USB 2.0 speeds.
2. Insert one end of a fiber Ethernet cable into the FIBER port of the TN-USB3-xx-01.
3. Insert the other end of the Ethernet network cable into an Ethernet port on the
other end.
4. If the TN-USB3-xx-01 is discovered by your computer, continue operation. Note that
the first time you plug in the TN-USB3-xx-01, it may take 2 full minutes for the driver
to install, before it begins working.
If the TN-USB3-xx-01 is not discovered, install the driver; see the “Driver
Installation” sections below.
Note that it will not appear as TN-USB3-xx-01; it will appear as the Asix chip (i.e., the
USB 3.0 to Gigabit Ethernet controller).

Troubleshooting
If a problem or exception occurs, perform these steps.
1. General: a) Do not connect too many USB devices to the computer. b) Wait 5
seconds after connecting the device before using it. c) Use powered USB hubs to
connect other USB devices. d) Do not connect USB devices when the system is busy
(i.e., running slower than normal).
2. If you are connecting to a USB hub, make sure it operates at USB 3.0 speed. Note
that the TN-USB3-xx-01 is a USB 3.0 device, but it also works at USB 2.1, 2.0, and 1.1
speeds. Make sure that any other USB devices are operating properly (native PC
USB port, USB hub, USB port on docking station).
3. If your computer does not recognize the TN-USB3-xx-01, make sure that the TN-
USB3-xx-01 is properly inserted into the USB 3.0 slot. Try starting the PC with the
TN-USB3-xx-01 plugged in to the USB port.
4. For maximum performance, connect the TN-USB3-xx-01 directly to a USB 3.0 port
on your computer. If you are connecting to a USB hub, make sure it operates at USB
3.0 speed and can provide the required power for this device.
5. Remove the TN-USB3-xx-01, and then reinsert it into the computer’s USB 3.0 slot
with the computer running.
6. Verify the Connectors and LEDs steps on page 5.
7. Verify the Connecting the TN-USB3-xx-01 steps on page 8.
8. Verify the Installing the Driver steps on page 10.
9. Try the Windows Driver Setup Program steps (see above).
10. Try the Manual Windows Driver Update (see above).
11. In Windows Network Connections, check for the presence of the TN-USB3-xx-01
device. In the example below, the Device Name is “AX88179 USB3.0 to Gigabit
Ethernet Adapter”.
12. See the Download Driver site for driver Readme files.
13. Review the Installation Overview on page 9and verify that the PC BIOS and USB
Host Controller drivers are current and power saving features are disabled.
14. Check the documentation that came with your computer for PC troubleshooting.
15. Try to troubleshoot the problem using Windows Device Manager. The TN-USB3-xx-
01 may be listed as "Unknown Device" or "Other Device" or the correct device name
may be displayed.

16. At Windows Control Panel > All Control Panel Items > Troubleshooting > Hardware
and Sound in the Network section select Network Adapter to display device
troubleshooting. Click the Next button or click the linked text “Advanced”.
17. Check your OS vendor documentation and website for troubleshooting steps / tools.
In Windows, try "Microsoft Fix it" or "Microsoft USB Hardware Verifier" or
"Microsoft System Restore". In Linux, check your distro's documentation and web
page for troubleshooting steps. For computers using non-Intel USB 3 xHCI
controllers, go to the manufacturer’s website and download and install the newest
driver.
18. At AXIS Properties > Advanced tab, select the Energy Efficient Ethernet property,
then at the Value dropdown make sure ‘Disabled’ is selected as shown below.
Having EEE enabled can cause dropped packets with some SFPs.
19. Contact TN Technical Support; see Contact Us on page 24 below.
